WINDOW-OYEBATING MECHANISM.

Application filed March 29, 1922. Serial No. 547,636.

Our invention relates to window operating mechanism of thetype which is adapted to simultaneously open and close a number of windows or ventilators arranged in a row in spaced or distant relation with respect to each other.

The general object of the invention is to provide not only a strong and durable construction of the character indicated but one which may be operated readily by the application of a minimum amount ofpower; also one which is efi'icient in operation.

To these and other ends our invention comprehends the construction as hereinafter fully described, particularly pointed out and defined in the claims and as illustrated in the drawings constituting a part of this specification, and in which Fig. 1 is a view showing a portion of a window in horizontal section and also showing the mechanism embodying our invention partly in plan and partly in horizontal section;

Fig. 2 is a frontelevation showing the means by which the mechanism is adapted to be operated;

Fig. 3 is a vertical sectional view taken on the line 83 of Fig. 1;

Fig. 4 is a perspective view of the means for pivotallly supporting the mechanism in operative relation with respect to the windows V I Fig. 5 1s a perspective view of an arm which is adapted to be pivotally connected to the left hand portion of the support shown in Fig. l,

Fig. 6 is a view showing in detail the mannor in which the window operating links are connected to the outer ends of the arms,

one of which is shown in Fig. 5; and

Fig. 7 is a vertical sectional View showing the manner in which the outer ends of the operating levers of themechanism are con nected to the operating rods or barsof the mechanism. y

In the drawings we have shown .a preferred form of construction embodying our invention, but it will beunderstood that said invention is susceptible of embodiment in other forms of construction than that shown and that various changes in the detailsot' construction may be made within the scope'of the claims hereunto appended without departingtrom said invention.

means are usually employed for the opening or-closiug of each window or ventilator although this is not essential. In the construction illustrated we have shown two sets of mechanism both of which are employed for the operation of a single window. set of the said mechanism is held and supported in reversed position with respect to the other. Both sets of mechanism are supported upon a short channel member 3 se cured to a column or post l, which comprises angle plates, as shown, by. means of bolts 5. The said channel member is provided with outwardly extending brackets 7 and 8, the former being connected to one end-portion of the lower flange of the chan nel member 3 while the other is connected to the opposite end portionot the upper flange of said channel member. nection is in part effected by means of rivets 9. Operating leversll and 12 are pivotally connected intermediate their ends by means or pivots 13 to the outer ends of the respective brackets 7 and 8. The outer ends of these levers 11 and 12 are pivotally conprovided each of the said levers with an opening 15 in which is journaled a boss or projection 16 which extends downwardly from the base 17 of an angle member 18having an upright portion 19 which is provided with an inwardly extending over-hanging flange portion 20. The said base is provided with an opening 21 which extends through the boss 16 and is also providedwith a V- Such conshaped notch 22 which extends transversely thereof, as shown in Fig. 7 Cooperating with the said angle member 1 8 is a clamping and holding block 25 provided with a 'notch 26 at its outer upper edge portion and also '26. The block is provided 'upon with an opening 27 adapted to be placed in aiinement with the opening 21. The inwardly e' tcnding over-hanging projection lead d'to be seat-ed within the notch its under side with a notch 23 which faces 22. The operating or actuating rods 1 1 and 15 are adapted to be located in these notches and clampeo and held between theblocks 25 and the bases 17 of the angle members 18. Bolts extend through the base '17; the

block and the outer end ot the levers 11 and 12'and the nuts and washers 31 on the opposite ends thereotoperate to clamp and hold the blocks .25 against the actuating or .l38138. The farm 35 with its angle member 37 is pivotally connected to the left hand end portion. of the channel 3 by means of a bolt 40 while thejarin 36 with its brace 38 ispivoted to theopposite end portion of the channel 3 by means of a pivot bolt 41. The bolts40 and 411 extend vertically through the'fianges of the said channel member and constitute additional means for securing the brackets 7 and 8 to the flanges of the channelmember 3. Theinner ends of the pivot levers 11 and 12 beyond their pivots 13 are 'pivotally connected to theinner ends of'links 42 and 43 while the votderencl's of the latter are pivotqally, connected to the arms 35 and 36 at points intermediate their ends, It will be noted that the pivots l3are-situated very much nearer to theinner ends of the levers .11 and .12th'an they are to their outer ends; and alsothat theouter ends of thelinks 12 jand t3 areconnectedsubstantially nearer to .the-pivots 40 and 11 of the arms 35 and 36 than to the outer endsof the said arms. The outer ends ofthe arms 35 and 36 are connected to the outer ends of links 415 which are in turn pivotally connected at theirin-ner endsto brackets or lugs 46 which are secu'redtothejbottom sash of the dow The-{connection to the brackets or lugs 4c6 is efiec'ted by means ofbolts 47. p

YConn'ection between the ends of the links e5 and'the outer ends ofthe arms 35 and36 is effectedmeans of bolts: 50 whiclieX tend through openings 51 in the outorends of said l nks andjfarms whlch bolts are pro;

1 "vided, with bearing'sleeves 52 which are of oval shape asindicatedin These v bear ng-sleeves are mounted; upon. the bolts 50 and are mterposed between thesame and the notch said links 42 and 13 to the portions of the walls of the said openings. The bolts are retained in posltion by means of the nuts and washers 53. 'The presence of the ovalsleevespermits relative r cl'ri ng move 'ment between the links 45 andthe arms 3:.)

or 36 as the casema-y be.

The positions of the pivots 13 with relation to the inner and outer ends of the levers 11 and 12 and the relation of the points of connection of the links 42 and 13 to the arms 35 and36 to the opposite ends of the latter and the relation of the length of the the levels 11 and 12 inwardly oi the pivots '13 should be such as to utilize as efficiently as possible the power applied to operate the mechanism to open and close the windows or ventilators. i I p The opposite ends of the operating or actuating; rods 14 and 15 are connected 'bv means of sprocket chains and 61 which are mounted on the sprocket wheel 62'and wheel 63 supporte upon shafts 61 and 65: also supported upon the shaft 641 is a worm gea1 jee with which. is engaged a worm '67 mounted pen a shaft 68 journaled in bearings 69. A pulley or sheave 70 is also supported upon the shaft 68 and is'adapted' to be driven by a cord or. band 71. By rotatinsg the sheave 70 in onedirection or the other the. sprocket wheel "62 throughthe worm 67 is rotated in a corresponding direction to actuate thesprocket chain 60 and pause horizontal. longitudinal movement of the actuating rods 14 and '15zin opposite directions.

Assuming that it is desiredto move the levers '11 and 12-froin the positions indicated full lines in Fig. 1 to the dotted line position shown therein, the rodsl l and 15 are actuated in the directions indicated by the arrows 72 and? 3. 'Such movement of the levers 11 and 12 operatesthroughthe links 42- and 13 to actuate the arms 35 and 36which through the links e5'c'auseopening movement of the win'dow to thedotted line position indicated. The rods, 1'41 and 15' 'shoiildbe moved in the opposite directions to those indicated by the arrows 72 and 73 to return the levers 11 and 12 from the dotted line positions shown in 'saidfigure to the full line positions shown'to eii'eot closing movement of the window.

Itfwill be seen that we have provided a simple and etlicient construction of 'mechanism which is adapted'to operate me. mostletlieie'nt'inanner to effect the opening and closing ofany numberot .XVlIlClOWS or ventilators simultaneously. H

Having thus described our invention,
